For all the candidates who have completed their engineering in Mechanical Engineering and want to prepare for the ESE, this book provides valuable guidance in many important aspects of the syllabus. This edition has been revised and updated to include the recent trends in the exam pattern and contains 16 solved papers with appropriate explanations to each problem. The reader gets a basic revision of the important topics in mechanical engineering, like theory of machines and vibrations, strength of materials, machine design. In the end, special topics like production engineering and industrial engineering have been discussed in great detail by citing examples from daily life. A lot of effort has been put to make the theorems easy to understand to avoid confusions. The book has a wide-ranging content for anyone who wishes to prepare for papers like ESE and other examinations for recruitment to posts of Mechanical Engineers.
